Answer:
Copernicus

According to astrophysicist Paul
Steinhardt, in an article about his concept of a cyclical cosmos: "This is a
revolution in the grand historic sense - in the Copernican sense. In fact, if
you think about Copernicus - from whom we derive the word revolution - his
importance was that he changed our notion of space and of our position in the
universe. By showing that the earth revolves around the sun, he triggered a
chain of ideas that led us to the notion that we live in no particular place in
the universe; there's nothing special about where we are.
